摘要
用采自北京六里屯垃圾填埋场的天然粘土对含有苯、二甲苯、三氯甲烷等有机污染物的模拟废水进行了吸附实验,并对吸附结果进行了分析,同时对主要含有伊利石、蒙脱石和高岭石的天然粘土的有机污染物吸附机理进行了初步探讨。实验结果表明六里屯垃圾填埋场的天然粘土对上述三种代表性的有机污染物的吸附率较差,基本在30%以下,不能有效防止垃圾渗滤液中有机污染物下渗污染地下水, 必须进行天然粘土的有机改性后才能作为填埋衬层使用。
By means of mensurating the composition of clay minerals and absorbing the organic compounds,the mechanisms of absorping the organic compounds are concluded and analysed.The absorption of the organiccompounds are very low,less than 30%.So the clay minerals which are mainly concluded by kaolinite、montmorillonite and illite are not organized can not been used as under layer in sanitary landfill.
